【摘要】 耐寒品种(HD₁₀₃×Ferumac)和不耐寒品种（张单9号）两种玉米黄化幼苗线粒体膜脂的磷脂均由磷脂酰胆碱、磷脂酰乙醇胺、磷脂酸、磷脂酰肌醇、双磷脂酰甘油和溶血磷脂酰胆碱等磷脂组分组成。各种磷脂组分的配比在两个品种之间差异不明显。两种玉米线粒体膜脂的脂肪酸组成,除最大两种脂肪酸组分（棕榈酸和亚油酸）外是近似的。更多还原

【Abstract】 The phospholipids of the mitochondria of chilling-sensitive（Zhang Dang No.9）and chilling-tolerant(HD₁₀₃×Ferumac)corn shoots are composed of phosphatidyl choline,phosphatidyl ethanolamine,phosphatidic acid,phosphatidyl inositol,diphospha- tidyl glycerol,lysophosphatidyl choline and so on.The weight per cent composition of va- rious phospholipid components in there two varieties of corn are not apparendy different. The fatty acid composition of the mitochondria of both corn shoots are similar except the palmitic acid and linoleic acid.更多还原
